Background: Prostate Specific Membrane Antigen-Positron Emission Tomography (PSMA-PET) is currently recommended to restage prostate cancer (PCa) and to guide the delivery of salvage treatments. We aim to evaluate the oncologic outcomes of patients with recurrent PCa who received PSMA-PET. Methods: 324 hormone-sensitive PCa with PSA relapse after radical prostatectomy who underwent PSMA-PET in three high-volume European Centres. Patients have been stratified as pre-salvage who never received salvage treatments (n = 134), and post-salvage, including patients who received previous salvage therapies (n = 190). Patients with oligorecurrent (≤3 lesions), PSMA-positive disease underwent PSMA-directed treatments: salvage radiotherapy (sRT) or Metastases-directed therapy (MDT). Patients with polirecurrent (>3 lesions) PSMA-positive disease were treated with systemic therapy. Patients with negative PSMA-PET were treated with sRT or systemic therapies or observation. The primary outcome of the study was Progression-free survival (PFS). Secondary outcomes were: Metastases-free survival (MFS) and Castration Resistant Pca free survival (CRPC-FS). Results: median follow up was 23 months. In the pre-salvage setting, the PFS, MFS and CRPC-FS estimates at 3 years were 66.2% vs. 38.9%, 95.2% vs. 73.7% and 94.9% vs. 93.1% in patients with negative vs. positive PSMA-PET, respectively (all p ≥ 0.2). In the post-salvage setting, the PFS, MFS and CRPC-FS estimates at 3 years were 59.5% vs. 29.1%, 92.7% vs. 65.1% and 98.8% vs. 88.8% in patients with negative vs. positive PSMA-PET, respectively (all p ≤ 0.01). At multivariable analyses, a positive PSMA-PET was an independent predictor of progression (HR = 2.15) and metastatic disease (HR 2.37; all p ≤ 0.03). Conclusion: PSMA-PET in recurrent PCa detects the site of recurrence guiding salvage treatments and has a prognostic role in patients who received previous salvage treatments.

Background: Prostate Specific Membrane Antigen-Positron Emission Tomography (PSMA-PET) is used to select recurrent prostate cancer (PCa) patients for metastases-directed therapy (MDT). We aimed to evaluate the oncologic outcomes of second-line PSMA-guided MDT in oligo-recurrent PCa patients. Methods: we performed a retrospective analysis of 113 recurrent PCa after previous radical prostatectomy and salvage therapies with oligorecurrent disease at PSMA-PET (≤3 lesions in N1/M1a-b) in three high-volume European centres. Patients underwent second-line salvage treatments: MDT targeted to PSMA (including surgery and/or radiotherapy), and the conventional approach (observation or Androgen Deprivation Therapy [ADT]). Patients were stratified according to treatments (MDT vs. conventional approach). Patients who underwent MDT were stratified according to stage in PSMA-PET (N1 vs. M1a-b). The primary outcome of the study was Progression-free survival (PFS). Secondary outcomes were Metastases-free survival (MFS) and Castration Resistant PCa free survival (CRPC-FS). Kaplan-Meier analyses assessed PFS, MFS and CRPC-FS. Multivariable Cox regression models identified predictors of progression and metastatic disease. Results: Overall, 91 (80%) and 22 (20%) patients were treated with MDT and the conventional approach, respectively. The median follow-up after PSMA-PET was 31 months. Patients who underwent MDT had a similar PFS compared to the conventional approach (p = 0.3). Individuals referred to MDT had significantly higher MFS and CRPC-FS compared to those who were treated with the conventional approach (73.5% and 94.7% vs. 30.5% and 79.5%; all p ≤ 0.001). In patients undergoing MDT, no significant differences were found for PFS and MFS according to N1 vs. M1a-b disease, while CRPC-FS estimates were significantly higher in patients with N1 vs. M1a-b (100% vs. 86.1%; p = 0.02). At multivariable analyses, age (HR = 0.96) and ADT during second line salvage treatment (HR = 0.5) were independent predictors of PFS; MDT (HR 0.27) was the only independent predictor of MFS (all p ≤ 0.04) Conclusion: Patients who underwent second-line PSMA-guided MDT experienced higher MFS and CRPC-FS compared to men who received conventional management.

Background: In February 2021 Medtronic ^® (Minneapolis, MN) launched the HUGO™ Robot-Assisted Surgery (RAS) System in the global market. The aim of the current study is to describe the first case series and the optimal setup of robot-assisted pyeloplasty procedure, performed with HUGO RAS system in a tertiary referral robotic center. Methods: Data from consecutive patients who underwent robot-assisted pyeloplasty at Onze-Lieve-Vrouwziekenhuis Hospital (Aalst, Belgium) were recorded. Baseline characteristics, and perioperative and surgical outcomes were collected. Results: Overall, 10 robot-assisted pyeloplasties were performed (October 2022–September 2023). Based on our expertise, the following minor setting changes have been made, relative to the official setup guide: the endoscope port and, subsequently, the left and right-hand ports were positioned more laterally. Additionally, the reserve/4th port was placed more laterally and cranially, and adjusted the arm cart's tilt angle, reducing it from −30° to −15°. The median docking time was 8 (interquartile range [IQR]: 7.2–9.8) minutes, and the median active console time was 89.5 (80.0–95.8) minutes. No conversion to open/laparoscopic surgery or perioperative complications was encountered. A single technical problem was recorded in 1 (10%) procedure. Specifically, one arm was blocked, and the procedure was accomplished with three arms without compromising the procedure success. Conclusions: This study represents the first worldwide series of robot-assisted pyeloplasty performed with the HUGO RAS system and shows promising results. The procedure might be safely performed with this robotic platform achieving optimal perioperative outcomes.

Introduction: Available guidelines recommend performing nephron-sparing surgery in selected renal cell carcinoma (RCC) patients. Many studies provided robot-assisted partial nephrectomy (RAPN) functional and oncological outcomes, with most of these including a wide timespan and a number of surgeons with different experiences, which might lead to the heterogeneity of the results. In this study, we aim to provide a contemporary report of RAPN patient outcomes performed at two referral centers by experienced surgeons. Materials and Methods: Overall, 333 RAPN patients treated at two European referral centers between 2019 and 2021 were identified. Continuous and categorical variables were reported using medians and proportions. Multi-variable logistic regression (MLR) models were fitted to test predictors of off-clamp technique use and trifecta achievement. Results: The median age was 65 (IQR: 57–73) years. The clinical stage distribution was as follows: 224 (67%) cT1a vs. 89 (26%) cT1b vs. 20 cT2 (7%). The median warm ischemia time was 14 (10–18) minutes, with trifecta being achieved in 74% (n = 240) of patients. In MLR models predicting off-clamp surgery, an increasing R.E.N.A.L. score was independently associated with a lower chance of attempting such a technique (OR: 0.69, p-value < 0.001). In models predicting trifecta achievement, both a higher R.E.N.A.L. score (OR: 0.78, p-value = 0.007) and the presence of multiple lesions (OR: 0.29, p-value = 0.007) were independently associated with lower chances of reaching the outcome. Significant upstaging of chronic kidney disease (CKD) stage was recorded in 9.4% of patients after one year of follow-up. Conclusions: We reported the contemporary outcomes of patients treated with RAPN by highly experienced surgeons from two referral centers. This report represents a valid benchmark that could be used for individual patient counseling in the decision-making process.

Background/Objectives: Robot-assisted radical cystectomy (RARC) has demonstrated improved perioperative outcomes and recovery in bladder cancer (BCa) patients. This study compares patient and tumor characteristics, operative time (OT), length of stay (LOS), and complication rates between a historical (2003–2016) and a contemporary cohort (2017–2024) treated at a high-volume robotic center. Methods: Data from 274 BCa patients who underwent RARC at AZORG Hospital, Aalst, Belgium, were analyzed. Perioperative outcomes were compared between cohorts. Multivariable Poisson regression models identified predictors of longer OT and LOS, while multivariable logistic regression models (MLRMs) assessed predictors of higher complication rates. Results: Overall, 274 BCa patients who underwent RARC were identified (38% historical cohort vs. 62% contemporary cohort). The contemporary cohort had a significantly shorter median OT (345 vs. 360 min; p = 0.048) and LOS (8 vs. 12 days; p < 0.001) compared to the historical cohort. Postoperative complications were lower in the contemporary group, with more cases experiencing no complications (60% vs. 41%) and fewer grade 3–4 complications (10% vs. 27%; p < 0.001). In multivariable Poisson regression, the contemporary cohort was an independent predictor of shorter OT (Incidence Rate Ratio [IRR]: 0.94, 95% [Confidence Interval] CI: 0.93–0.96; p = 0.04) and shorter LOS (IRR: 0.65, 95% CI: 0.60–0.69; p < 0.001). In MLRMs predicting complications, the contemporary cohort was associated with lower risk (Odds Ratio: 0.42, 95% CI: 0.23–0.76; p = 0.005). Conclusions: RARC outcomes improved significantly over time, with reduced OT, LOS, and complication rates in the contemporary cohort, highlighting advancements in surgical techniques, perioperative care, and patient safety. These findings reinforce the role of RARC in optimizing BCa treatment.
